Such a device is herein illustrated smd cnicult f a i faggot as an indicating voltmeter V comprising a My mventlon resldes 1n the apparatus, suitably journaled shaft lOocarrying a gear mechanism and features of construction of 11 meshing h a k 12 connected t th 40 .hhe Character hereinafter described and wheel 7. Shaft 10 is provided with a rotas5 claimed. I y tion-restraining spring or element 13 one end For an illustration of one of the forms my 7 of whi h may be secured to a portion 14 of invention may take, reference is to be had to the instrument frame.

the accompanying drawings, in which Shaft 8 is suitably journaled, as indicated 45 Figure 1 is a schema ic p an vie of the at 15 and 16 13 1 9 f ameof the devicaan 0 is free to rotate a gear wheel 17 secured thereto in accordance with the rotational movement of wheel 7. The worm gear 17 is suitably meshed with, to drive a gear wheel 18 that is secured to a shaft 19. The meters A and V, in the example shown, are connected to, or actuated by, the same electrical circuit. The meter A rotates continuously in accordance with the product of the ampere-hours of the circuit and therefore, member 1 is rotated at a speed proportional to the magnitude of that quantity. Simultaneously, the shaft of meter V is moved to a position dependent upon the magnitude of the voltage of said circuit and the member or wheel 7, which is controlled thereby, assumes a position with respect to the member 1 which depends upon, said voltage magnitude. Accordingly, shaft 19 rotates at a speed proportional to the prod, net of the volts and ampere-hours of said electrical circuit. Since the wheel or member 7 coacts directly with the member or disk 1 and is movable with respect'thereto in response to oscillatory movement of the shaft J -10, it follows, upon decrease in voltage, that said member '7' approaches the center of disk 1 and the shaft 19 is rotated at decreased speed, provided therot'ative speed of disk 1 does not materially change. Conversely,

" "should the voltage increase, the wheel 7 recedes from the center of disk 1 and, under the conditions just stated, shaft 19 rotates at increased speed. I

Rotative or oscillatory movementof shaft 19 may be utilized in any desired manner. By way of-eXample, shaft 19 has been illustrated as actuating indicating or recording mechanism of thec'haracter disclosed in United States patent to Mylius,No.'1,580,523, granted April 13, 1926. "Vhenthus utilized, shaft 19 may have a gear keyed thereto, Fig. 3, which meshes with and drives a gee-r26 keyed to a suitably j ournaled shaft 27 having a worm screw 28 secured to one end thereof. 'Mounted on an arm or lever 29 is a shaft 30 having secured thereto a worm wheel 31 which normally meshes with the aforesaid worm screw 28. Shaft 30 also carries a p1n- I ion 32meshing with a gear wheel 33 mounted on a suitably ournaled shaft 34,upon which gear wheel 35 is also disposed. .The latter meshes with a gear wheel 36 mounted on a suitableournaled shaft 37 having a biasing weight 38 secured thereto. Carried by the shaft37 is a pointer or indicating member 40.

I A second pointer-39'comprising an. actuating part 3960 adapted-tdbeengaged bypointer 40, whereby said pointer 391s moved in a clockwise direction, Figais provided for indicating themaximum travel the pointer 40.

The aforesaid lever 29 is connected: to a pivot pin or shaft 41 jmoiuitedin suitable -bearin s not shown; Secured to the shaft 41 5 b 7 V 7 is an arm or member 42 oiased upwardly, as

viewed in Fig. 3, against an adjustable stop 43 by a spring 44, or the like.

Coacting with one end of the lever 29 is a cam 45 carried by a shaft 46 rotated at a substantially constant speed by a suitable device, not shown, but which may be of the character illustrated in the aforesaid Mylius patent.

Assuming that the pointers 39 and 40 are at the zero position of thescale 47, rotation of shaft 19, under the influence of the mechanisms A and V illustrated in Figs. 1 and 2, I

of volts and ampere-hours for the period.

which elapsed while the pointers were moving from zero tothe position just mentioned.

Immediately after worm wheel 31 was disengaged from worm'screw 28, as described above, the'weight'38 swung downwardly, Fig. 3, to restore pointer 40-to its zero position.

After'the action last described, the high point of cam 45 passes from'the end of lever 29 with consequent reengagement of the worm wheel 31 with the worm screw 28, whereupon shaft 19 again functions to impart a cycle of movement'tothe pointer 40, the length of which is of any desired value, as fifteen minutes, more or less.

If desired, shaft 27, through the gear mechanism illustrated may. be'utilized for actuating the shafts 48,49, 50 and 51 of a suitable gear train-by which the indicatingpointersof suitable integrating mechanism '52 are controlled. I

The aforesaid pointer 39 serves to indicate the maximum demand-to which-the apparatus is responsive and remains in the maximumdemand-indicating position until manually reset.

Itshall be understoodthat members 1 and 7 maybe actuated'otherwise than asherein described. Thus, forexamplaan ammeter may be substituted for the meter'A in which case, whenthe, voltmeter Y is utilized, as indicated, the shaft 17 .partakes of oscillatory movement only and its position is dependent upon the volt-ampere magnitude of the electrical circuit to which the ammeter and voltmeter are connected.

While I have illustrated but one embodiment of my inventiolnit will be apparent to those skilled in the art that various changes, modifications, substitutions, additions and I omissions may be madein the apparatus illus-' trated without departing 'from'the spirit and l scope of my invention, as set forth in the appended claims. V
